Rotary splicing structure

Abstract

A rotating splicing structure includes a connecting rod with at least one first connecting part for connecting and fixing to an external component. It also includes at least one rotating connector sleeved on the connecting rod and rotatably connected thereto. Damping is provided between the rotating connector and the connecting rod. The rotating connector has a second connecting part for connecting and fixing to the external component. The advantages of this invention are: the rotating connector can be rotated to any position as needed by the operator, thus breaking through the fixed angle of perpendicularity between adjacent connectors in traditional connectors. This allows toys assembled using this structure to be assembled in multiple angular directions, improving playability and enjoyment while reducing costs. Furthermore, the damping between the rotating connector and the connecting rod prevents the rotating connector sleeved on the connecting rod from shifting along the connecting rod's direction.

Description

Technical Field

[0001] This utility model relates to a splicing structure for a toy, and more particularly to a rotating splicing structure. Background Technology

[0002] Adapters in building blocks are typically made of plastic or metal. Depending on their design, they allow parts of different shapes, sizes, or types to connect to each other. Adapters usually have specific shapes and sizes that allow them to mate with other parts and provide a secure connection during assembly. These parts can be connected by inserting, rotating, or pressing, making it easy for users to assemble toys and build different structures or models.

[0003] Chinese patent document CN218443520U discloses an intermediate adapter, which includes at least three connecting parts that are connected and fixed together and connected to other parts by a snap-fit ​​method, and the central axes of two adjacent connecting parts are perpendicular to each other.

[0004] The above solution can form a stable connection with other toy components, thereby expanding the toy's playability. However, the above solution has the following drawbacks: since several connecting parts are fixed together, the angle between adjacent connecting parts cannot be changed. This means that other parts in the toy can only be connected to the adapter in a fixed direction, which reduces the toy's playability. If different angles need to be spliced, other connecting parts need to be produced and configured, which will increase the production cost of the complete toy set. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rotating splicing structure that enhances the playability of toys.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotating splicing structure, comprising a connecting rod, wherein the connecting rod is provided with at least one first connecting part for connecting external components and fixedly cooperating with the external components, and further comprising at least one rotating connecting head sleeved on the connecting rod and rotatably connected to the connecting rod, wherein a damping is provided between the rotating connecting head and the connecting rod, and wherein the rotating connecting head is provided with a second connecting part for connecting external components and fixedly cooperating with the external components.

[0007] The beneficial effects of this utility model are as follows: the rotating connector, sleeved on the connecting rod and forming a rotating connection with the connecting rod, allows the rotating connector to be rotated to any position as needed by the operator. This breaks through the fixed angle where adjacent connectors are perpendicular to each other in traditional connectors, allowing toys assembled using this splicing structure to be assembled in multiple angular directions without adding parts. This not only improves playability and fun but also reduces costs. Furthermore, the damping between the rotating connector and the connecting rod can be provided by other components such as damping rings, or a slightly tightened relationship can be formed between the rotating connector and the connecting rod, thereby preventing the rotating connector sleeved on the connecting rod from shifting along the direction of the connecting rod.

[0008] Furthermore, one end of the rotating connector is provided with a rotating ring that is sleeved on the connecting rod and rotates in cooperation with the connecting rod. The rotating ring and the connecting rod are damped. There are at least two rotating rings and a sleeve space is formed between adjacent rotating rings.

[0009] A slight tightening fit is formed between the rotating ring and the connecting rod to provide damping for the rotating connector, preventing it from sliding on the connecting rod. Furthermore, at least two rotating rings create a fitting space between adjacent rings for other rotating connectors to be fitted onto, thus enabling the splicing of multiple rotating connectors. This staggered fitting connection method ensures that the second connecting portions of two rotating connectors are on the same plane when they are connected. This fitting space also limits the movement of the interconnected rotating connectors along the connecting rod direction.

[0010] Furthermore, the rotating connector is provided with an abutting and limiting surface, which abuts and limits the movement of adjacent rotating connectors.

[0011] In adjacent rotary connectors, the abutment limiting surface of one rotary connector abuts against the connection point between the rotating ring and the rotary connector of the other rotary connector to limit the rotation limit of the rotary connector. As an optional preferred solution, the angle between the two adjacent rotary connectors after abutment limiting is achieved can be set to 90°. This not only gives it unique rotational characteristics but also the same functionality as most adapters on the market that are set at right angles to each other, further improving the toy's playability.

[0012] Furthermore, the connecting rod is provided with an anti-detachment component, which cooperates with the rotating ring to prevent the rotating connector from detaching from the connecting rod.

[0013] The anti-detachment component can be installed on only one side of the rotating ring to prevent the rotating connector from detaching from the connecting rod, and the damping between the rotating connector and the connecting rod can be used to prevent the rotating connector from sliding on the connecting rod. Alternatively, the anti-detachment component can be installed to cooperate with the rotating rings on the upper and lower sides of several rotating connectors to completely lock the position of the rotating connector on the connecting rod. In this case, the damping between the rotating connector and the connecting rod can fix the rotating connector at a certain rotation angle, so as to prevent the problem of the rotating connector's rotation angle being uncertain due to slight torque pushing the rotating connector.

[0014] Furthermore, the anti-detachment component includes two pressing components symmetrically arranged at the end of the connecting rod and capable of moving towards each other. Each pressing component is provided with an anti-detachment plate, which extends from the end of the connecting rod toward the direction of the rotating ring and its cross-section overlaps with the rotating ring at least partially.

[0015] The pressing component is elastic and has a certain gap with the connecting rod to allow for opposing movement. When the rotating ring slides on the connecting rod and moves to the end of the connecting rod, part of the rotating ring will abut against the anti-detachment plate, thereby preventing the rotating connector from detaching from the connecting rod. Furthermore, the opposing movement of the pressing component can release the locking relationship between the anti-detachment plate and the rotating connector. Thus, when the rotating connector is damaged or needs replacement, it can be removed from one end of the connecting rod, and the damaged rotating connector can be replaced, improving the efficiency of the splicing structure and reducing maintenance costs.

[0016] Furthermore, it also includes a splicing component that can be inserted into the first connecting part or the second connecting part. Both the first connecting part and the second connecting part are provided with locking holes. One end of the splicing component is symmetrically provided with two unlocking parts and the two unlocking parts can move towards each other. The unlocking part is provided with a locking part that cooperates with the locking hole to lock. A splicing hole that can cooperate with external components is formed between the two unlocking parts.

[0017] The assembly piece is inserted into the inner hole of the first or second connecting part, and the locking part and locking hole cooperate to fix the assembly piece to the first or second connecting part. Since the unlocking parts can move in opposite directions, the locking part can be pulled away from the locking hole to release the fixed cooperation, and the assembly piece can then be removed. Furthermore, the assembly hole between the two unlocking parts for assembling with external components further enhances the playability of the assembly toy. As an optional feature, a baffle can be provided on the end face of the assembly piece where the unlocking part is located. This baffle prevents external components fitted onto the first or second connecting part from detaching from it.

[0018] Furthermore, the thickness of the locking part gradually increases from the end face along the splice insertion direction toward the direction away from the splice insertion direction.

[0019] The above configuration allows the locking part to first contact the inner wall of the first or second connecting part through its thinner portion during the insertion of the splice into the first or second connecting part, reducing the difficulty of mating. Furthermore, this thinner portion occupies only a small proportion of the overall locking part, thus ensuring a stable connection between the two parts when they engage and lock with the locking hole, achieved through the thicker portion of the locking part.

[0020] Furthermore, it also includes a locking member that mates with the locking hole to lock the external component onto the first or second connecting part. One end of the locking member is provided with a locking pin that mates with the locking hole for locking, and the other end of the locking member is provided with a locking groove for use with a turning tool.

[0021] After rotation, the locking pin can form a limit with the locking hole, thereby locking the external component on the first or second connecting part; the locking groove located at the other end of the locking part and used in conjunction with the turning tool makes operation easier and simplifies the operation.

Detailed Implementation

[0023] It should be noted that the external components are not limited to the two types of round tube 5 and perforated round tube 6 mentioned in this embodiment, but can also be other shapes. Furthermore, the first connecting part 11 and the second connecting part 21 mentioned in this embodiment, as well as the first locking hole 111 and the second locking hole 211 respectively provided on them, have the same external dimensions.

[0024] An embodiment of this utility model provides a rotating splicing structure, as follows: Figure 1-6 As shown: This includes connecting rod 1, rotating connector 2, splicing component 3, locking component 4, and external components (not shown in the figure). The structure of each component is briefly described below.

[0025] Both ends of the connecting rod 1 are provided with first locking holes 111, and the first connecting part 11 is fixed by locking members 4 inserted into the first locking holes 111 and the holes on the external components. An anti-detachment member 12 is provided on the end face of one of the first connecting parts 11 on the connecting rod 1. The anti-detachment member 12 includes two symmetrically arranged pressing members 121. The two pressing members 121 have a certain elasticity and there is a certain movement gap between them and the connecting rod 1 to allow the pressing members 121 to move towards each other. Each pressing member 121 is provided with an anti-detachment piece 122. The anti-detachment piece 122 extends from the end of the connecting rod 1 toward the rotating ring 22 and its cross-section overlaps with the rotating ring 22 at least partially. That is, when the rotating connector 2 slides on the connecting rod 1 and tries to detach from the connecting rod 1, the rotating ring 22 of the rotating connector 2 will abut against the anti-detachment piece 122 and be prevented from detaching from the connecting rod 1 by the anti-detachment piece 122.

[0026] One end of the rotating connector 2 has two rotating rings 22, which form a slightly tightened fit with the connecting rod 1 to prevent the rotating connector 2 from sliding on the connecting rod 1. This also ensures that the rotating connector 2 can be rotated to a certain angle, preventing movement due to slight torque. The other end of the rotating connector 2 has a second locking hole 211, and a second connecting part 21 is fixed by inserting a locking element 4 into the second locking hole 211 and a hole on the external component. A fitting space 221 is formed between the two rotating rings 22, allowing other rotating connector 2's rotating rings 22 to be fitted and rotated within it. An abutment limiting surface 23 is provided on the rotating connector 2 near the rotating rings 22. When adjacent rotating connectors 2 rotate to a perpendicular position, the abutment limiting surface 23 abuts against the connection point between the rotating ring 22 and the rotating connector 2 of another rotating connector 2, thus limiting the rotation of the rotating connector 2.

[0027] One end of the splicing component 3 has a splicing hole 33 at its center for connection with an external component. A baffle 32 extends from the edge of the splicing hole 33 away from its center. Two unlocking parts 31 are symmetrically arranged at the edge of the splicing hole 33. Each unlocking part 31 has a certain elasticity and a certain gap between itself and the baffle 32 to allow the unlocking parts 31 to move towards each other. The unlocking part 31 has a locking part 311 that cooperates with and is fixed to the first locking hole 111 or the second locking hole 211. The thickness of the locking part 311 gradually increases from the end face along the insertion direction of the splicing component 3 towards the direction away from the insertion direction of the splicing component 3.

[0028] The first locking hole 111 has a circular center, and arc-shaped holes are provided at both ends of the circular hole in the same radial direction. The locking part 311 is circular and mates with the circular hole at the center of the first locking hole 111 to fix the splicing piece 3 and the connecting rod 1. One end of the locking piece 4 is a locking pin 41, which can only pass through the first locking hole 111 when it is at a certain angle. When the locking pin 41 rotates, the other end of the locking piece 4 is a locking end face 43 that is adapted to the surface of the perforated round tube 6. The locking pin 41 and the locking end face 43 mate to fix the perforated round tube 6 on the first connecting part 11. The center of the locking end face 43 is provided with a locking groove 42 that mates with the turning tool (not shown in the figure) provided in the splicing toy to rotate the locking piece 4.

[0029] The following is a brief description of the cooperative relationship between the rotating connector 2 and the connecting rod 1 in this embodiment: After the rotating rings 22 of the two rotating connectors 2 are fitted together, the two anti-detachment plates 122 are pressed to drive the two pressing parts 121 to move towards each other, thereby allowing the two rotating connectors 2 to be fitted onto the connecting rod 1. After the connection between the rotating connector 2 and the connecting rod 1 is completed, rotating the rotating connector 2 can adjust the angle of the rotating connector 2 to the splicing angle required by the operator. At this time, the damping between the rotating ring 22 and the connecting rod 1 not only prevents the rotating connector 2 from sliding on the connecting rod 1, but also allows the splicing angle to be determined after rotating to the splicing angle required by the operator.

[0030] The following is a brief description of the cooperative relationship between the rotating connector 2 or connecting rod 1 and the splicing piece 3 in this embodiment. Since the first connecting part 11 and the second connecting part 21 on the rotating connector 2 and the connecting rod 1 have the same external dimensions, it is only briefly described here that a round tube 5 is sleeved on the second connecting part 21 and the splicing piece 3 completes the connection between the two. After the round tube 5 is sleeved on the second connecting part 21, while pressing the two unlocking parts 31 and making them move towards each other, the splicing piece 3 is pressed into the inner hole of the second connecting part 21. Since the unlocking part 31 is elastic, when the locking part 311 on the unlocking part 31 moves to the center of the second locking hole 211, the locking part 311 rebounds and cooperates with the second locking hole 211 to complete the connection between the splicing piece 3 and the second connecting part 21. At this time, the baffle of the splicing component 3 abuts against the round tube 5 to prevent the round tube from coming off the second connecting part 21. It should be noted that the external component round tube 5 has no holes, which can be used to cover the second locking hole 211 on the second connecting part 21 so that the assembled toy is more aesthetically pleasing.

[0031] The following is a brief description of the locking relationship between the rotating connector 2 or connecting rod 1 and the perforated tube 6 in this embodiment, which is fixed by the locking member 4: Since the first connecting part 11 and the second connecting part 21 are the same size, only the connection and fixing relationship between the perforated tube 6 and the second connecting part 21 is described here. After the perforated tube 6 is fitted onto the second connecting part 21, the center of the hole on the perforated tube 6 overlaps with the center of the second locking hole 211. Then, the locking member 4 is passed through these two holes in sequence. After rotating the locking member 4 with an external turning tool, the locking pin 41 on the locking member 4 is pressed against the inner wall of the second connecting part 21, while the locking end face 43 abuts against the perforated tube 6. The two cooperate to complete the fixing between the perforated tube 6 and the second connecting part 21.

[0032] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
